, To al l 'who m it vma'g concern: 1

Beit known that I, ELIJAH Buss, a citizen of the United States, residing at Dean, in the county of Stillwater and. State of ,Montana, have invented certain new and -useful Improvements in' Automatic Train- Stops; andI do hereby declare the following to be a full, clear, and exact description L j.of the'inventiomsuch,as will 'enable others -10 skilled in the art to which it appertains to 1 niake and use the same.

The present invention relates to improvemerits in automatic train stops, and has for its principal-object to, provide an automatic mechanism for turning off thesteam from the locomotive cylinders, and simultaneously 1 applying the air brakes and blowing the grouped together-rinwhistle whenever the engineer inadvertently runs pasta signal-set at-danger.

- It is'- an0ther object of the present inventionl to provide ,niec-hanism for accomplish ing these several doses which shall be I simple arrangement, and be capable of readyactuation from a trip oriobstaclie. that is set by means of the semaphore. signal.

The invention will be more Particularly setout in the following description which is views, and in which z to, be taken in conjunctionwith the accompam in'g drawings, inwhich similar symbols lndicate likeparts throughout the several Figure -1 is a side elevational view of-a L locomotive partly broken away, but :shown as th amechanism constructed in h the present invent-ion p plan view thereof; 3s sectional View oft-he track 'levation and partly in secg apparatus, and indotted equipped accorda 41s "a perspective View of a device independent of the signal for operating the locomotive mechanism.

Referring inore particularly .to'the draw ings, a locomotive 1 is illustrated as traveling onaltirack 2, passage over which is under the jcontrol of the usual semaphore signal 3 carrieclona shaft linthehollow tower -5. A short length of chain 6 runs 'overand engages a series of pins? fitted in an enlarged portionS of the shaft within 1 The ends 1 ofjthe chain 6 a are connected to flexible wire cables 9- and 10 which are carthe locomotive equipment;

a ngles end of 5, and pulleys 11 and 12' The outer ends of these wire cables 9 and 4 10 are coupled to the opposite ends'of a chain length 1-1, engaging pins 15 on an en-' larged part 16 of a second shaft 17, journaled close to'the track 2, as shown more particularly in Figs. 2 and 3. The enlarged part 16 of' the shaft 17 also movably supports an inverted hshaped trip or obstacle 18 which, when the semaphore 3' is in the danger position shown in Fig: 3, is adapted to stand upright and to engage either of a pair of arms 19' and 20 on the opposite ends ofa rock shaft 21 journaled on the forward part of the locomotive 1.

This rock shaft 21 carries a segment 22-, which receives at its opposite sides the divided ends 23 and 24- of a flexible wire cable 25. This cable is directed oversuitable pullevs 2G and 27, and includesan elastic tension device 28. The rear divided ends 29 and 30 of the flexible cable 25 pass in opposite directions over pulleys 31 and 32. and are coupled, respectively, to the lever 33 of the air brake appliance and an arm '31- for turning steam into the whistle 35.

A second arm is joined to the flexible cable 25 by suitable connections 36 and 37, and such arm controls the openingand closing of a steam valve indicatedat 38 in with the direction in which the engine is-'- running, will'strike the trip or obstacle 18,

which will cause the shaft 21- on the locomotive'to be rocked 1n either a clockwise or counter c'lockwise direction according as the engine is running in a forward or reverse "direction.

7 This rocking of the shaft 21 will cause a draft on'either one of the divided ends or 24, which will result in aforward pull;

The force'and ar on the flexiblecable 25. of this pull-will be absorbed in the elastic tension device 28; This forward pull on the cable will operate to swing the 'arm 35 the brakes, and the other divided rear 30 will operate the arm 31-, thus blowing the through the connection 37, thereby closing the steam valve 38; while at the same time the divided rear end 29 will pull the air brake lever 33 to bleed the air line and apply end whistle. 35. After actuation'the air brake lever may be drawn rearwardly to again close the system, which will draw rearwardly .upon the fieXible ca le 25 and through the connections steam valve arni35 to the initial position with the steam line open.

Of course, when the semaphore 3 is moved to the clear track position the shaft i will be actuated, turning the pins 7 which engage the chain length 6, and in turn actuate members of a post which are bent from a" single sheet of metal having its ends i3 and,

ii bent at right angles to the post to engage the upper face of. a tie indicated at 45, and

with its extremities forming flanges 46 and 4:7 for embracing the sides of the tie, and having struck-in portions providing-prongs for taking afirm hold of the same.

The above parts are made from spring -metal in order topermit the flanges 46 and 47 to normally spread apart-to a distance capable of readily receiving the tie, and being afterward; clamped together by a cam head i9. on onejend of a revoluble shaft 50 and by a lever 5l having a cam face 52 also adapted to engage the opposite flange 4:7. 7

A cross bar 53 is secured in any-desired manner to the post, and .is adapted tobeplaced insuch a position. on the cross. tie as to engage either of'the arms 19 or 20 on thelocomotive to actuate the same-in a inanner J similar. to the trip or. obstacle 18. The-outerend-ofthe at 54:,- to provide a socket in Which-is placed.

cross bar 53 is rolled, as indicated a red or other flag 55, and is .also formed with .a notch 56 in which may be hungthe bail of a red or other lantern 57. I

This device is adapted to be carried by the brakeman on the rear end of the train, and

when said train becomes stalled in the middle of a block such device is to-becarried by the brakeman to a suitable distance in rear of thetrain, where it is to be fixed to across tie by the operation of the lever 51 and cams l9 and and thesame will give a visible signal by means ofthe flag and lantern 57, andhvhiclr, if the engineer disregards,

36 will return the and an air brake appliance, yournaledat the forward part of said locopending from said rock shaft v1 'ing beyond both sides rear fiagmcn, section crew or other .em- .ployees, where it can'be used in case of derailment, 'ashout, or other accident,

The rock shaft-can be carried by electric locomotive, and when connected properly to brakes. on electric locomotive will bring said electric locomotive to stopin the-same manner as locomotive propelled by steam.

The arms 19 and 20 taper downwardly. so as to be lighter at their lower ends where they come in contact with the'trip 18, in on der to strike an easier blow; and to further this object the trip 18 is cushioned. with a piece of rubber hose 18" which prevents the, two pieces which are of metal coming; in direct contact.

lVhere l have specifiedn the claims steam locomotive and'steam valve, the same are to be understood as equally well referring toan electric locomotive and its controller to 1 which my invention is in. like manner ap plicablc.
